refactor(provider): TET Phase3老接口内部委托Fetcher——①四老方法(get_price/get_closes_panel/get_index_stocks/get_fundamentals_df)旧体删除,改调同款Fetcher(与_ex两张皮,strict契约自此对老接口生效:非法frequency/fq/count/日期/空列表→ValueError,查询失败raise;Phase2副本对照4/4语义等值已验issue#19)②qfq因子二次读库归一:_build_qfq_factor/_apply_qfq_batch拆为_read_qfq_rows+_qfq_factor_from_rows与_read_qfq_events+_apply_qfq_events(IO/纯计算),因子读全挪进extract_data,transform零IO③all_weather四处get_fundamentals_df(choice)补空守卫(空候选集=调用方业务态)④3个宽松断言回归测试改strict(1m频率/空stocks/空symbols);938绿 [vps]
